You have to understand, that all the automatic methods, be it adaptive sampling, labeling, etc, work in most cases, but it is always possible to break them. This can happen when you are plotting very small values or very large one or when your function has very small features. For those cases, you can often manually adjust the settings.

For the ticks you have several options. First, you can set them manually to any label you like

Here, the strings I used can be any representation of the values you like. Furthermore, you can use a function which takes xmin and xmax of your plotting interval and gives back a list of tick information

There are some more options and you can look at the documentation for Ticks to find out more. Finally, you could post-process an existing plot, by extracting the created Ticks and adjust them. With AbsoluteOptions you can extract the given Ticks of a Graphics and then it is simple replacement
